1. PWM stands for:
   1. Pin Work Mode.
   2. Pulse Weight Modulation.
   3. Pulse Width Modulation.
2. In the Intel Galileo Gen 2 board, the pins labeled with the following symbol as a prefix for the number can be used as PWM output pins:
   1. Hash sign (#).
   2. Dollar sign ($).
   3. Tilde symbol (~).
3. A 100% duty cycle (always signal in the ON status) in a PWM pin will generate a steady voltage equal to:
   1. 0 V.
   2. The voltage specified in the position in which the IOREF jumper is located.
   3. 6 V.
4. A 0% duty cycle (always signal in the OFF status) in a PWM pin will generate a steady voltage equal to:
   1. 0 V.
   2. The voltage specified in the position in which the IOREF jumper is located.
   3. 6 V.
5. A 50% duty cycle in a PWM pin with a LED connected to it will generate the same result as a steady voltage ...
